Test your syweb installation by pointing your browser to the URL http://${VHOST_HOSTNAME}/${VHOST_APPDIR}/configtest.php If you don't want any user interaction, move index_noui.php to index.php. syweb expects a /*.rrd style directory structure under /var/lib/symon/rrds. Customize ${MY_INSTALLDIR}/setup.inc if this is incorrect for your setup.
